Abstract: A jersey which provides enthusiasts of such sports as baseball and basketball an interchangeable two in one jersey. The jersey allows the wearer to quickly convert the standard jersey into a jersey with long sleeves. The attachable long sleeves are stored in pocket-like enclosures which also have zippers along the jersey sides. The sleeves are attached using a pair of hidden sleeve zippers or a pair of Velcro strips. The sleeve zippers are hidden by an overlap of jersey material to give the appearance of a normal garment when worn as a standard jersey or a converted long sleeve jersey. The Velcro strips are positioned along the outer edge of the arm openings of the basketball jersey. The top portion of the Velcro strip attached to the jersey folds out for easy connection of long sleeves.
